Outlook has updated its Authentication method and Thunderbird has not adapted

[maelochs]

Outlook now uses OAuth2/Modern Auth for SMTP servers, which Thunderbird does not offer. This means I cannot send emails from one of my oldest  and most widely spread email addresses. 

Thunderbird is always asking for donations; I have never donated. If (and only if) you update your protocols so I can continue to use my Outlook (Hotmail) address, I will finally send you some money.

I know you have no reason to trust me, but take a chance. Maybe I can restore some of your faith ion the decency of humanity---after you restore my email access.

I have the same problem, even with 128.3.3esr.

as workaround I use davmail and it allows me to continue to use Thunderbird as it is unreplacable 🙂
